I am an electronic engineer doing mostly embedded device programming. Lately I want to switch fields to become from a half behind IT guy to a full IT pro.
The two field I am interested in are:
1. Embedded linux development
2. Oracle DBA (specialize in tuning)
From my brief salary surveys it seem that on average the DBA pays higher than the rest of other IT discipline like networking, security, application programming, and embedded linux programming.
For instance in Singapore:
In UK, DBA pays slightly higher than embedded linux developers.
Now why is that? IMHO embedded linux developers requires to know a large amount of material eg linux kernel, system programming, device drivers, embedded system architecture, i/o hardware (each one whole book), C, and wireless network.
From my studies, DBA seems to require to study a comparative much smaller amount of material eg SQL, network administration, and tuning. Database concept for me are much easier to absorb than embedded systems.
But yet DBA seems to pay higher than embedded linux developers. Is this true based on your experience?
If true, why are DBAs paid higher than the rest? I read a couple of DBA books, all seem to mention that DBAs are required to survive on pizzas, not sleep for 4 days, and handle a long line of angry managers etc (other tech books never seems to mention career requirements). Is this the main reason?
